Aims: The aim of this study is to assess the effects of early, immediate, and progressive loading of dental implants clinically and radiographically. Materials and Methods: Twenty implants were inserted in 20 patients. Five implants were used for each group (early, immediate, progressive, and conventional loading). In early loading, implant was loaded after 1 week. In immediate loading, loaded with temporary crown within 48 hours then definitive prosthesis after 4 months. In progressive loading loaded with temporary crowns out of occlusion after 3 months for the mandibular sites and 4 months for the maxillary ones for 1 month, and then loading on centric occlusion for 1 month, then full occlusion for 2 months, then definitive prostheses were used. Radiographic assessment for crestal bone loss was done. Clinical assessment of periodontal pocket depth was performed at 3, 6, and 9 months. Results: At 9 months, probing depths were 1.80 ± 0.37, 2.10 ± 0.34, 2.25 ± 0.18, and 1.83 ± 0.38, for immediate, early, progressive, and control groups, respectively. Immediate group showed statistically nonsignificant bone loss after 3 months in the mesial side but showed statistically significant bone loss after 6 and 9 months whereas statistically significant bone loss through all periods in the distal side. Early group showed statistically significant bone lose. Progressive group showed statistically nonsignificant bone loss after 3 months but significant loss after 6 and 9 months. Control group showed statistically nonsignificant bone loss. Conclusions: Immediate loading showed excellent soft-tissue reaction, and early loading responses are identical to conventional two-staged procedure. Progressive loading demonstrated significantly less crestal bone loss than conventional one. [ABSTRACT FROM AUTHOR] |
